Skeleton of the African Elephant
The African elephant averages 3 meters high, but the largest one ever measured was a specimen shot in Angola in 1956, and was almost a full meter taller than average. The smallest elephants were the dwarf elephants that existed in Crete (and whose funny skulls are strongly suspected to have led to the cyclops tales), and they were no bigger than a large pig.
